I don't think these dropped packets are viewable with tcpdump. At least I haven't seen a set of packets in a tcpdump that matches the number of dropped packets. I supposed there may be more than one type of packet being dropped, but that is very difficult to tell.
TCP retransmissions
The newest NAASC VM Host (naasc-vs-2) shows over 100 TCP retransmissions per second when doing iperf3 tests. Other nodes like naasc-vs-3 and naasc-vs-4 do not show these at all. While I can't say these TCP retransmissions are indicative of a problem, they could become a problem with increased load and they certainly will make debugging more difficult when there is a problem. I suggest the reason for these TCP retransmissions be found and resolved.
